Anyone who calls 911 should be prepared to answer questions that include:

The location of the emergency, including the street address

The phone number you are calling from

The nature of the emergency

Details about the emergency, such as a physical description of a person who may have committed a crime, a description of any fire that may be burning, or a description of injuries or symptoms being experienced by a person having a medical emergency

The site also states anyone who dials 911 by mistake should not hang up because that could make 911 officials think that an emergency exists, and possibly send responders to your location. Instead, officials say you should simply explain to the 911 operator what happened.
